Abstract (en)

There is provided a base station including a downlink channel generator, a reference signal generator, and a transmitter. The downlink channel generator generates a downlink channel for a terminal. The reference signal generator generates a first demodulation reference signal or a second demodulation reference signal which is a demodulation reference signal associated with the downlink channel and is enabled to be multiplexed between a plurality of antenna ports. The transmitter transmits the downlink channel and transmits the first demodulation reference signal or the second demodulation reference signal selected based on a configuration for the terminal. Granularity of the first demodulation reference signal is different from granularity of the second demodulation reference signal in a resource block.
